The sun is not only a source of warmth and good mood, especially in the cold season. It can cause a lot of problems when on vacation by the sea or in the mountains, to a driver on the road, while hunting, fishing, or even just while walking. The eyes are especially vulnerable to its radiation, for which it is important to choose the right means of protection. Most often they are used by sunglasses, the choice of which must be approached carefully. What color of glasses is better to prefer?
Pros and cons of glass
First of all it gets up the question of choosing the material from which the lenses are made. There are two main groups: glass and various polymer materials. Each of them has its own advantages and disadvantages.
Glass lenses, which look stylish and expensive, are popular among fashion lovers. In addition to appearance, they have a number of undeniable advantages. The material is very durable, it is difficult to scratch it, the glass is resistant to possible temperature changes.Lenses made from it reliably protect the eyes from exposure to ultraviolet radiation. But they also have their drawbacks. Glasses with glass lenses are heavy, break easily and break when dropped.. The latter is especially critical for car owners, because in the event of an accident, glass fragments can cause serious injuries.
Lenses of different colors also have their own characteristics. They differ different levels of protection against ultraviolet radiation and are used in various cases.
Important! You should select glasses not by color, but according to their purpose.
Greens
Green lenses are option for motorists. They slightly distort color reproduction without disturbing the perception of the surrounding reality, but increase contrast. This property is especially important when driving, where a quick assessment of the situation and reaction to its changes is required. Also, glasses with such lenses are suitable for going out into nature on bicycles.
Purple
Glasses of violet or blue colors perfectly protect the eyes from bright sunlight, as well as cut off infrared radiation. However, they are strictly contraindicated when driving a car. Also, you should not wear them for a long time, as this may adversely affect your eye health. In most cases, such glasses can only be useful as a fashion accessory.
Black
This is a classic and simple option for those who don’t want to be bothered by choosing glasses. Such lenses provide good color reproduction and protect the eyes from the bright sun. In the case of black glasses, you need to take into account that very dark glasses are not always good. Lack of light can cause the pupil to dilate and put more strain on the eyes.
Yellow
Yellow and gold lenses cut off the blue part of the spectrum. They are recommended to be worn on cloudy and rainy days. Glass of these shades improves visibility in fog or in low light conditions - at dawn and dusk. They also have the property of reducing tension in the optic nerves. They are also suitable for outdoor sports - tennis, volleyball or badminton.
Colors close to yellow-brown would be ideal for fishing trips, hiking along open water or where there is a lot of snow. They protect the eyes from excessively bright or reflected light. Even darker lenses are suitable for drivers due to their ability to increase contrast and reduce fatigue.
Gray
Glass shades of gray are distinguished by high-quality color rendering. They are equally absorb rays of the color spectrum and can be considered a universal choice for different situations.
Light gray mirror lenses are recommended for mountain tourism. At high altitudes, sunlight reflects off snow caps and is especially dangerous for vision, causing corneal burns (ophthalmia). In these conditions, eye protection becomes especially important.
Chameleons
Chameleon lenses, also called photochromic, change their color and degree of darkening depending on the light level. The spectrum is quite wide - from light gray to almost black. This ability makes them a versatile choice that will suit a variety of conditions. Wherein you can't use them while driving. Car windows do not transmit ultraviolet rays, which cause the lenses to darken or lighten.
